By creating unique characters. If the characters with the 'useless bloodline' have distinct personalities, goals, and backstories, it can make the fanfic engaging. For example, a character who is constantly trying to prove the value of their bloodline against all odds.
One example could be a fanfic where the so - called 'useless bloodline' actually has hidden powers that are slowly revealed. It might start with the character being underestimated because of their bloodline but then they find a unique way to use it in battles.
Make the emotions real. If Naruto is blinded, show his fear, his determination to overcome it. That will draw readers in.
You could also make the fanfic interesting by setting it in different time periods. Start with the past when Naruto's grandfather and Madara were in their prime. Show their battles or interactions. Then jump to the present where Naruto discovers some relic or memory related to them. This time - traveling aspect, even if it's just through memories, can add a lot of depth and intrigue to the fanfic.
Incorporate time - travel elements. With his immortality, Naruto could be sent back in time to change certain events in the Naruto universe. This would open up a whole new world of possibilities, like preventing some of the major tragedies that occurred in the original story or changing the fates of certain characters.
It can create a lot of conflict. For instance, other clans might see the character with double bloodline as a threat and try to eliminate them. This would drive the plot forward as the character has to constantly defend themselves.
To make a 'Naruto Hinata stalker fanfic' more interesting, you could introduce some mystery elements. For instance, the identity of the stalker could be a mystery at first. Is it someone from the Hidden Leaf Village? Or is it an outsider? This would keep the readers guessing.
The most interesting feature is the unique power set. The necromancer bloodline allows for abilities like raising the dead or communicating with spirits, which is very different from the normal Naruto jutsu.
One way to combine Naruto and Spider - Man in a bloodline fanfic could be through some sort of magical or scientific experiment. Maybe a mad scientist in the Naruto universe tries to combine the DNA of a shinobi with that of a radioactive spider. This could result in a character having both the abilities of a ninja like Naruto, such as using chakra to perform jutsus, and the powers of Spider - Man, like climbing walls and shooting webs. Another possibility is that in a multiverse - type scenario, Naruto somehow ends up in the Spider - Man universe and through some strange encounter, his bloodline gets mixed with the mutagen that gives Spider - Man his powers.
First, you need to research the Naruto universe thoroughly. Know the existing bloodlines, the ninja clans, and the world - building. For the Erosion Bloodline, think about what unique abilities it could have, like maybe the ability to erode an opponent's defenses or chakra. Then, create a compelling character with this bloodline. Give them a backstory, goals, and flaws.
The story can be made interesting by adding twists. For instance, Naruto could be initially in love with someone else, and Sakura has to fight for his heart. This creates drama and suspense.
